Abstract (en)

[origin: WO2019194820A1] An example device includes a first chamber to contain a first fluid and a second chamber to contain a second fluid. The first chamber includes a first fluid outlet, and a first bubbler to ingest bubbles into the first chamber when pressure in the first chamber overcomes a first bubble pressure of the first bubbler. The second chamber includes a second fluid outlet, and a second bubbler to ingest bubbles into the second chamber when pressure in the first chamber overcomes a second bubble pressure of the second bubbler. An outlet node is fluidly connected to the first fluid outlet and the second fluid outlet. The outlet node draws the first fluid from the first chamber when the first bubbler ingests bubbles, and sequentially draws the second fluid from the second chamber when the second bubbler ingests bubbles.
